Hillary leaves point a traveling due east at a constant speed of 40 miles per hour. after hillary has driven 22 miles, her brother, arnold, leaves point a also traveling due east on the same road. at what constant rate of speed, in miles per hour, must arnold drive in order to catch up to hillary in 2 hours?

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

b. f(x) = –√x + 3this is the correct answer

y=20x
